Abstract

Meta-analysis of 28 controlled studies on the efficacy of rational-emotive therapy (RET) showed RET to be superior to placebo and no treatment but equally effective in comparison with other types of treatment such as combination therapies and systematic desensitization. No support was found for the view that RET with a main or balanced emphasis on behavioral techniques is more efficacious than RET with a primarily or exclusively cognitive approach. However, given the heterogeneity of the set of studies and its relatively small sample size, interpretations of results have to be made with caution, particularly because evidence was found for a relationship between study characteristics and magnitude of effect size. For the sake of meta-analysis, outcome studies should be required to report at least the means and standard deviations for all experimental groups.
